First: See a trustworthy Muslim doctor and follow their instructions. Some tips that might help you if the doctor agrees to them are: you are not a disbeliever and you are not held accountable for thoughts, so take this as a rule you do not break: never retake your shahadah and never repeat anything you doubt. Say I believe in Allah and His messengers, seek refuge from the shaytan and stop there without following the thought, cut off what leads you back into the habits.
